Common Side Effects of Cat Vaccination & How to Manage

It's not uncommon for cats to exhibit adverse reactions after receiving vaccinations, which is somewhat related to the mechanism of antibody production. However, these reactions typically do not last long and cats usually recover on their own. This article aims to provide an indepth look at the common adverse reactions following vaccination in cats, along with the measures to address them.

Part 1: Causes of Adverse Reactions After Vaccination

The vaccines cats receive are generally weakened viruses designed to stimulate their immune systems to produce antibodies. During this process, cats may experience some adverse reactions, which are a normal part of the process. Not all cats will have adverse reactions after vaccination, and the severity can vary greatly depending on the cat's individual constitution. If a cat shows severe adverse reactions, it's important to seek veterinary care promptly.

Part 2: Common Adverse Symptoms After Vaccination

Common adverse reactions following vaccination in cats include lowgrade fever, depression, loss of appetite, drowsiness, and weakness. Some cats may also experience symptoms like facial swelling, itching, and diarrhea. In severe cases, breathing difficulties and shock can occur. Typically, mild symptoms after vaccination should diminish and disappear within 1 to 2 days. If a cat exhibits severe symptoms like persistent vomiting, it's advisable to take it to the vet immediately. Some cats may develop local abscesses, which are the body's overreaction to the vaccine and not due to infection caused by the vaccine itself.

Part 3: Reducing Side Effects After Vaccination

Before vaccination, have your cat undergo a thorough physical examination to ensure it is in good health. If your cat is sick or unwell, wait until it recovers before scheduling the vaccine.

If your cat has had a history of allergic reactions after vaccination, inform your veterinarian in advance. Choose a different vaccine brand and closely monitor your cat's reaction after vaccination.

After vaccination, stay with your cat for at least 30 minutes at the vet's office before leaving. Also, keep an eye on your cat at home, as some allergic reactions may not manifest until 24 hours postvaccination.

In case of severe adverse reactions, treat the symptoms promptly. Avoid vigorous exercise, bathing, and keep the injection site clean.

Follow the vet's instructions for postvaccination care. For instance, keep your cat indoors for a week after vaccination to prevent exposure to stray cats or those with potential diseases.

In addition, if your cat's adverse reactions persist beyond two days, it's crucial to seek veterinary attention.

In summary, while adverse reactions in cats after vaccination are normal, if symptoms are severe or linger, it's essential to seek veterinary care promptly.
